Description

TECHNICAL FIELD

[0001] The application relates to the technical field of femoral artery hemostasis devices, and in particular to a femoral artery hemostasis device. BACKGROUND

[0002] At present, femoral artery compression hemostasis is mainly achieved in a physical compression manner. Physical compression hemostasis is divided into two forms. One is rotary compression, and a femoral artery visible compression hemostat disclosed in Chinese Patent Document No. CN221932056U discloses that a compression block is driven against a bleeding point by a rotary screw rod to generate compression force so as to achieve the purpose of hemostasis.

[0003] The other is a gas bag type, and the gas bag is inflated by an external air pump or a pressurized syringe, and the gas bag is inflated to expand to compress and hemostasis the bleeding point.

[0004] Generally, when a patient is injured, bleeding not only exists in the femoral artery, but also exists around the femoral artery. By means of the above-mentioned screw rod abutting and gas bag compression, compression of the femoral artery can be achieved. The compression of the femoral artery can indeed reduce the bleeding amount of the patient. However, a gap is generated between the bandage near the compression ball and the leg of the patient, and the bleeding amount of the wound around the femoral artery is not easy to be inhibited, and thus improvement is needed. CONTENT OF THE UTILITY MODEL

[0005] In order to facilitate synchronous hemostasis of the femoral artery and the bleeding point around the femoral artery of the wound of a patient, the application provides a femoral artery hemostasis device.

[0006] The application provides a femoral artery hemostasis device adopting the following technical scheme:

[0007] The femoral artery hemostasis device comprises a visible hemostasis ball, an elastic bandage and an adjusting piece. The elastic bandage is provided with a fixing hole for embedding and fixing the visible hemostasis ball. The visible hemostasis ball is fixed in the fixing hole by sewing and bonding. The surface of the hemostasis ball is flush with the surface of the elastic bandage. The side of the hemostasis ball that is in contact with the skin of the patient is in an ellipsoidal shape. The two end sides of the elastic bandage are movably connected and partially overlap. The adjusting piece is used for adjusting the overlapping area of the elastic bandage.

[0008] By adopting the technical scheme, when hemostasis is performed on the wound of the femoral artery of the patient, the medical staff presses the visible hemostatic ball on the wound of the patient, the ellipsoidal surface of the visible hemostatic ball is tightly attached to the wound, and the bleeding of the femoral artery is reduced. Meanwhile, the elastic bandage is wound on the thigh of the patient, and the area of the two end side overlapping regions of the elastic bandage is adjusted by the adjusting member. The elastic bandage is tightly wound on the thigh because the outer surface of the hemostatic ball is flush with the surface of the elastic bandage. Therefore, the visible hemostatic ball is pressed by the elastic bandage, and effective hemostasis is facilitated.

[0009] The area of the two end side overlapping regions of the elastic bandage can be adjusted according to the condition of the patient by the adjusting member and the elastic bandage. Therefore, the hemostasis effect is good for different patients.

[0010] Optionally, the elastic bandage is an elastic bandage, the adjusting member includes a rough surface arranged on one end side of the elastic bandage and a hook surface arranged on the other end side of the elastic bandage, the hook surface is movably connected with the rough surface, and the length of the rough surface is greater than that of the hook surface.

[0011] By adopting the technical scheme, the hook surface and the rough surface are arranged. When hemostasis is performed on the femoral artery of the patient, the medical staff tightens the elastic bandage, the elastic bandage is tightly wound on the leg of the patient, the hook surface on one end side of the elastic bandage is movably connected with the rough surface on the other end side of the elastic bandage, the elastic bandage is fixed, and stable tightening and hemostasis are achieved.

[0012] In order to improve the comfort of the patient, the elastic bandage is arranged in the form of an elastic bandage, and the skin friendliness of the elastic bandage is improved.

[0013] Optionally, the side of the visible hemostatic ball that is attached to the skin of the patient is provided with a hemostatic member, the hemostatic member includes a chitosan hemostatic sheet that is movably connected with the side of the visible hemostatic ball that is attached to the skin of the patient, the chitosan hemostatic sheet is arranged in a plurality of groups, and the chitosan hemostatic sheet is attached to the position of the visible hemostatic ball above the wound of the patient according to the bleeding position.

[0014] By adopting the technical scheme, the pressure compression hemostasis only slows down the bleeding of the patient and does not achieve real hemostasis. If the pressure is slightly reduced, the femoral artery will still bleed a lot. Therefore, the chitosan hemostatic sheet arranged at the bottom side of the visible hemostatic ball is used to quickly hemostasis and coagulate the bleeding of the femoral artery, and promote the healing of the wound. Meanwhile, the chitosan hemostatic sheet provides a moist, slightly acidic and enzymatic debridement healing environment for the wound. Meanwhile, the good biocompatibility of chitosan reduces the risk of stress reactions such as rejection reactions of the body.

[0015] Meanwhile, by arranging a plurality of groups of chitosan hemostatic pieces, when the wound surface is small, only one group of chitosan hemostatic pieces can be arranged to perform hemostasis and healing on the bleeding site; when the wound surface is large or the wound is large, a plurality of groups of chitosan hemostatic pieces are arranged to cover the wound, thereby achieving rapid hemostasis and blood coagulation.

[0016] Optionally, the adjusting member comprises an adjusting buckle sleeved on the end side of the elastic band, the adjusting buckle is provided with adjusting holes along the two ends of the elastic band in the length direction, the two adjusting holes correspond to the two ends of the elastic band one by one, an adjusting wheel is rotatably arranged on the adjusting buckle, adjusting teeth are fixedly bonded on the two end sides of the elastic band, and a tooth groove is formed in the outer peripheral wall of the adjusting wheel.

[0017] By adopting the above technical scheme, when the elastic band is fixed by the magic tape with a hook surface and a hook face, medical staff need to pull the elastic band tightly to wrap and tighten the patient's thigh, which requires high requirements for medical staff, and by the form of the adjusting wheel, the medical staff inserts the two end sides of the elastic band into the two adjusting holes respectively, so that the adjusting teeth on the two elastic bands correspond to the tooth groove of the adjusting wheel, at this time, the medical staff rotates the adjusting wheel to gradually increase the area of the overlapping part of the two end sides, thereby realizing compression hemostasis of the femoral artery and the wound of the patient.

[0018] And the two end sides of the elastic band are arranged in the form of adjusting teeth, which makes the two end sides move during adjustment, so that the visible hemostatic ball is not easy to move during the process, thereby realizing stable compression hemostasis of the femoral artery.

[0019] Optionally, the adjusting teeth at the two ends of the elastic band are oppositely arranged, and the adjusting teeth at the two ends of the elastic band are located on opposite sides of the adjusting wheel, that is, when the adjusting wheel rotates, the two ends of the elastic band move oppositely / contrarily, and the adjusting buckle is further provided with a limiting member for limiting rotation of the adjusting wheel.

[0020] By adopting the above technical scheme, the adjusting teeth at the two ends of the elastic band are arranged in the form of opposite arrangement, when the medical staff rotates the adjusting wheel, the two ends of the elastic band move oppositely at this time, thereby tightening and compressing the thigh of the patient by the elastic band, thereby realizing hemostasis, and after tightening, the limiting member is arranged to prevent the adjusting wheel from rotating reversely, thereby realizing stable hemostasis and blood coagulation.

[0021] Optionally, the two end sides of the elastic band are subjected to hardening treatment.

[0022] By adopting the technical scheme, the two end sides of the elastic bandage are subjected to hardening treatment, in order to improve the skin adhesion of the elastic bandage, the elastic bandage is an elastic bandage, the elastic bandage is soft and not easy to directly pass through the adjusting hole, and the femoral artery hemostasis needs to be done in seconds, therefore, the end sides of the elastic bandage are subjected to hardening treatment, so that the medical staff can pass through the adjusting hole, thereby reducing the hemostasis time, improving the hemostasis efficiency, and reducing the bleeding amount of the patient.

[0023] Optionally, the limiting member comprises a limiting rod elastically and slidably arranged in the adjusting buckle, one end side of the limiting rod is movably inserted into the tooth groove of the adjusting wheel, and the end side of the limiting rod movably abuts against the tooth groove of the adjusting wheel.

[0024] By adopting the technical scheme, when the relevant medical staff rotates the adjusting wheel to keep the elastic bandage stable and tight for hemostasis of the thigh of the patient, the elastically arranged limiting rod is inserted into the tooth groove of the adjusting wheel, so that the adjusting wheel is not easy to reversely rotate, stable and tight hemostasis is achieved, the gap between the hemostatic bandage and the skin of the patient is reduced, and stable hemostasis of the wound around the femoral artery is also achieved.

[0025] Optionally, an adjusting groove is formed in the outer surface of the adjusting buckle, a push rod is fixedly connected to the limiting rod, the push rod is slidably arranged in the adjusting groove, and the end side of the push rod is movably flush with the outer surface of the adjusting buckle.

[0026] By adopting the technical scheme, when the relevant medical staff slides the push block to separate the limiting rod from the tooth groove of the adjusting wheel, the free rotation of the adjusting wheel is achieved, and the elastic bandage is conveniently unlocked;

[0027] Meanwhile, the push rod is arranged in flush with the outer surface of the adjusting buckle, so that the unlocking caused by accidental collision is reduced, and the stability of the hemostat is improved.

DETAILED DESCRIPTION

[0037] The following will be described in detail in combination with the accompanying drawings. Figures 1-4 The present application will be further described in detail.

[0038] The embodiment of the present application discloses a femoral artery hemostat.

[0039] Embodiment 1

[0040] With reference to Figure 1 A femoral artery hemostat comprises an elastic bandage 11 and a visible hemostatic ball 1 sewn and pasted on the elastic bandage 11, the elastic bandage 11 is provided with a fixing hole 12, the visible hemostatic ball 1 is fixedly embedded in the fixing hole 12, the upper surface of the hemostatic ball is planar, the lower surface of the visible hemostatic ball 1 is ellipsoidal, the lower surface of the visible hemostatic ball 1 is movably attached to the wound of the femoral artery of a patient, and the elastic bandage 11 is further fixedly pasted with a square pressing plate 13 which is attached to the upper surface of the visible hemostatic ball 1, the two end sides of the elastic bandage 11 are movably connected and partially overlapped, and the femoral artery hemostat further comprises an adjusting member 2 for adjusting the area of the two end side overlapping regions of the elastic bandage 11.

[0041] With reference to Figure 1 and Figure 2 In order to improve the comfort of the patient, the elastic bandage 11 is an elastic bandage.

[0042] The adjusting member 2 comprises a hook surface 22 sewn on one end side of the elastic bandage 11 and a rough surface 21 sewn on the other end side of the elastic bandage 11, and the hook surface 22 and the rough surface 21 are adaptively pasted.

[0043] And in order to more efficient realization of the femoral artery hemostasis, the side of the visible hemostatic ball 1 which is in contact with the patient's skin is provided with a hemostatic member, which is a chitosan hemostatic piece 15 in this application, and the chitosan hemostatic piece 15 is pasted on the position of the visible hemostatic ball 1 above the patient's wound.

[0044] And the chitosan hemostatic piece 15 is provided with several groups, and according to the wound area and wound size of the patient's femoral artery, the chitosan is set as one group, two groups, etc. When the wound area is small, only one group of chitosan hemostatic piece 15 can be set to stop bleeding and heal the wound. If the wound area is large, or the wound is large, multiple groups of chitosan hemostatic piece 15 are set to cover the wound, thereby achieving rapid hemostasis and coagulation.

[0045] The chitosan hemostatic piece 15 provides a moist, slightly acidic and enzymatic debridement healing environment for the wound, and at the same time, through the good biocompatibility of chitosan, reduces the risk of stress reactions such as body rejection reactions.

[0046] The implementation principle of the femoral artery hemostat in Example 1 of the application is as follows: when hemostasis is performed on the patient's femoral artery, the relevant medical staff first presses the visible hemostatic ball 1 on the femoral artery wound, so that the chitosan hemostatic piece 15 corresponds to the wound, and then tightens the elastic band 11 to tighten the elastic band 11 on the patient's leg, and then the hook surface 22 on one end of the elastic band 11 is bonded with the hair surface 21 on the other end, so as to realize the fixation of the elastic band 11, and then realize the stable tightening and hemostasis.

[0047] Example 2

[0048] Reference Figure 3 And Figure 4 The difference between this embodiment and Example 1 is that the adjusting member 2 includes an adjusting buckle 23, one side of the adjusting buckle 23 is in contact with the patient's thigh skin, and the side of the adjusting buckle 23 in contact with the patient's thigh skin is coated with silicone gel, the adjusting buckle 23 is provided with adjusting holes 25 at both ends along the length direction of the elastic band 11, the two adjusting holes 25 correspond to the two ends of the elastic band 11 one by one, and the adjusting buckle 23 is provided with an adjusting wheel 24 which is rotatably arranged on the adjusting buckle 23, the adjusting wheel 24 is coaxially provided with a knob 242 which protrudes from the outer surface of the adjusting buckle 23, the two end sides of the elastic band 11 are fixedly bonded with adjusting teeth 26, and the outer peripheral wall of the adjusting wheel 24 is provided with a tooth groove 241, and the adjusting teeth 26 are engaged with the tooth groove 241.

[0049] It should be noted that the adjusting teeth 26 at both ends of the elastic band 11 are oppositely arranged, and the adjusting teeth 26 at both ends of the elastic band 11 are located at opposite sides of the adjusting wheel 24. When the elastic band 11 needs to be tightened on the leg of the patient, the medical staff rotates the adjusting wheel 24 to move the two ends of the elastic band 11 relative to each other, so that the elastic band 11 is tightened to stabilize the femoral artery and the surrounding wound to stop bleeding.

[0050] Since the elastic band 11 is made of elastic bandage material, the elastic bandage material is soft and not easy to pass through the adjusting hole 25 directly. The femoral artery needs to be stopped bleeding in a short time. Therefore, in order to solve this problem, the two ends of the elastic band 11 are hardened in this application, so that the medical staff can pass through the adjusting hole 25, thereby reducing the bleeding time.

[0051] Meanwhile, when stabilizing and tightening to stop bleeding, the adjusting wheel 24 is not easy to rotate, so the limiting member 27 is further arranged on the adjusting buckle 23. The limiting member 27 includes a limiting rod 271 slidingly arranged in the adjusting buckle 23. The sliding direction of the limiting rod 271 is consistent with the length extension direction of the elastic band 11. One end of the limiting rod 271 is movably inserted into the tooth groove 241 of the adjusting wheel 24. The other end of the limiting rod 271 is fixedly connected with a limiting spring 272. The other end of the limiting spring 272 is fixedly connected with the adjusting buckle 23. The limiting spring 272 is in a compressed state in the initial state. When the adjusting wheel 24 is rotated to tighten the elastic band 11, the end side of the limiting rod 271 abutting against the tooth groove 241 is inclined.

[0052] Meanwhile, in order to facilitate unlocking of the adjusting wheel 24 and reduce accidental touch, the limiting rod 271 is fixedly connected with a lever 273. The adjusting buckle 23 is provided with an adjusting groove 274. The lever 273 is slidingly arranged in the adjusting groove 274. The sliding direction of the lever 273 is consistent with the sliding direction of the limiting rod 271. The end side of the lever 273 is flush with the surface of the adjusting buckle 23.

[0053] The implementation principle of the femoral artery stop bleeding device in the embodiment 2 is as follows: when the femoral artery of the patient needs to be stopped bleeding, the medical staff first inserts both ends of the elastic band 11 into the adjusting hole 25, so that the adjusting teeth 26 are engaged with the tooth groove 241. Then the medical staff rotates the knob 242 to rotate the adjusting wheel 24, so that the two ends of the elastic band 11 move close to each other to tighten the leg of the patient. At the same time, the tooth groove 241 of the adjusting wheel 24 abuts against the inclined side of the limiting rod 271, so that the limiting rod 271 slides away from the adjusting wheel 24 until the stable bleeding is achieved. At this time, the limiting rod 271 is inserted into the tooth groove 241 under the action of the elastic restoring force, thereby achieving the locking of the adjusting wheel 24.

[0054] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
